CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 279,658, dated June 19, 1883.

' Application filed November 10, 1882. (No model.)

lings; and it has for its object to provide anef ficient coupling that can beoperated without going between the cars, that will effectually and automatically couple with cars of varying heights, and that will play laterally and vertically.

In the drawings, Figure 1 is a front view of my improved draw -head. Fig. 2 is a top View thereof,'showing two engaging draw-heads coupled. Fig. 3 is a vertical central longitudinal sectional view. Fig. 4 is a vertical transverse sectional view on the line it a", Fig. 3. Fig. '5 is a like view on the line 3 3 Fig. 3, and Fig. 6 is a vertical longitudinal sectional view .through the coupling-hook receivingchamber.

Referring to the drawings,'A designates the main or central draw-head, which has the mouth B, a top, G, bottom D, and rear wall,,E, its sides being open, as shown. The top 0 and bottom D are formed with a vertical pin-perforation, F, near the mouth B, to enable a coup y ling to be effected with cars having the ordi nary pin-and-link coupling apparatus.

G is a block, which is pivoted between the top 0 and bottom D, in rear of perforation F, by means of a vertical pivot-bolt, H, passing through the draw-head. In the rear end of block: G is formed a bearing, I, for the central cylindrical portion, J, of the cross-piece K, said cylindrical portion being retained in its bearing by binding-straps L L, extending from block G, and conforming to the shape of portion J. The cross-piece K can,,by means of this above-described connection with block G, swing laterally in either direction as the block turns on its pivot, or it can swing vertically in its own bearings on said block. The crosspiece K has at one end a head, M,carrying a coupling-bar, N, and at its other end a receiving-chamber, O, for the coupling-bar of the adjoining draw-head. Head M and chamber O of course swing with erosspiece K, so that they canbe coupled with cars of varying height-s and swing laterally by motion of the ears. I j

I To provide for returning the cross-piece K toitsnornial position, I provide aeoiled spring, P, connected with .the cylindrical portion 3, and extending to and connected with the back wall, E, of the draw-head A.

The coupling-bar N is cylindrical, and is formed with an arrow-pointed head, Q. The bar N passes through the head M, and is re tained therein by a shoulder, R, at the front and pin S at the rear.

The chamber 0 comprises a bottom, T, sides U U, and a top, V, the latter being hinged between sides U U by a cross-pin, V, at the front, and resting on shoulders X X at the rear of sides U U. The back of this chamber is open, as shown, and its mouth Y, at the front, is sur rounded by a flaring guideflange, Z. From the top of this flange projects a rearwardlyextending spring, A, which bears on hinged top V to retain itdown in its normal position.

The coupling-bars N rest normally with their beveled edges of the arrow-head in a vertical plane, and as the draw-heads approach in coupling the bars enterythe opposite chamber 0 of the, otherdraw-head. Asthe bar N en-. 'T 3 ters its ch amber the arrow-head forces the hinged top thereof up until it is passed, when the top falls and locks the bar in by the arrowhead.

To provide for ready uncoupling, a trans verse rod, B, is arranged to extend through chamber 0, the portion J ,and head M, and is provided at the side of chamber 0 with an operating-arm, O, and at the side of head M with an arm, D, at right angles to the body of the rod. Inside chamber 0 an arm, E, projects laterally from rod B and engages the hinged top V, so that it will be raised as the rod is turned by its handle and admit of the arrow-head being withdrawn. As rod B is turned to effect this its arm D moves in a slot, F, in a plate, G, fixed on the end of bar N, so that the latter is turned of the same. By this construction, when rod B is turned it effects complete uncoupling. Rod B is preferably provided with a lateral plate or flange, H, inside chamber 0, which assumes a vertical position when the rod is turned. Then as the arrowhead passes through the chamber in uncoupling it engages this plate H and forces .it down, thus throwing over the rod B, so that the parts all assume their normal position, ready for couplin 1 is a line extending from the end of arm 0 to the top of the car, whereby the operation can be effected from the latter point.

I claim as my invention 1.. The combination of a central draw-head having a top, bottom, and back wall, a laterally-swinging block pivoted between said top and: bottom, a cross head or piece having bearings in said block and carrying coupling-heads, whereby the cross-head can swing vertically and laterally, and a returning-spring extending from the central portion of the cross-head to the rear wall of the draw-head, as set forth.

2. The combination of the central draw-head, having open sides and carrying a pivoted laterally-swinging block, a crosshead comprising a central portion 11 aving bearings in said block, whereby it swings laterally and vertically, and provided at one end with a head carrying a headed coupling-bolt and at the other end a bolt-chamber having a hinged top, as set forth.

3. The hereindescribed receivingichamber for a headed coupling-bolt, having a flaring guide-flange at its month, an open back, and

a hinged top that is retained down by springs extending from the flange, and provided with ing a hinged top and open back, of a cross-rod having a lateral arm for lifting said top and a lateral flange or plate inside the chamber to be engaged by the conplingbolt in uncoupling to return the cross-rod to its normal position,

as set forth.

In testimony that I claimthe foregoing as my own I have hereto affixed my signature in presence of two witnesses.
